In each of the 21 states, it is legal not to hire people who use nicotine, company officials said. Employers in 17 states are also legally allowed to test for nicotine, officials said.

U-Haul International has not indicated if it would conduct tests, officials said.

Company executives encourage employees not to use nicotine by waiving a required wellness fee, officials said. The company doesn’t require tobacco users to pay a health care insurance premium, the Republic reported.

The company said it has made strides to encourage health and wellness including breaking ground on a new conference and fitness centre in Arizona and implementing various employee fitness and wellness programs.

Some hospitals and other health businesses have implemented no-nicotine hiring policies, company officials said.
